WebScientists think that convection currents that move the plates flow in Earth's. The mantle of Earth is made partly of magma. When magma rises and sinks, this is called … Web5 apr. 2024 · Below the lithospheric plates, the mantle ispartially molten and can slowly flow in response to steady forces applied for long periods of time. When solid rock in the Earth's mantleis subjected to heat and pressure in the Earth's interior over millions of years, it can be softened and molded to different shapes.

The Force That Drives The Tectonic Plates - Earth Surface

WebIn places where convection currents rise up towards the crust’s surface, lithospheric plates move away from each other in a process known as seafloor spreading. For … Web12 mei 2024 · When it sinks down, it breaks it apart (compressional force). These tensional and compressional forces are what drive plate tectonics. They break apart the whole lithosphere into 7 major plate tectonics and 12 or so minor ones. Now, that we know mantle convection tears the brittle lithosphere apart which is also called “slab pull”. grace church on brown mesa az
